Two-way traffic refers to a road system where vehicles can travel in both directions. This setup is common in urban areas, allowing for efficient movement of cars, buses, and bicycles. Proper signage and lane markings help ensure safety and organization on these roads. In a two-way traffic system, drivers must be aware of oncoming vehicles and follow traffic rules to prevent accidents. Traffic signals and stop signs play a crucial role in managing the flow of vehicles, ensuring that each direction has a chance to move safely. This system is essential for maintaining order on busy streets.
